ANSWER:

0

SOLUTION:

1) The y-intercept is the value of the function, for x = 0.

2) So, to find the y-intercept when you have the function, you need to solve the equation for y when x = 0.

For example if the function is y = f(x) = x^2 + 5, the y-intercept is y = f(0) = 0^2 + 5 = 5. 3) Graphically, the y-intercept is the point

where the graph of f(x) crosses the y-axis.

So, if you have the graph, you just read the value of the function on the y-axis.

Taking all that information, you do not report the y-intercept as a pair of coordinates. The y-intercept is reported just as a value for y.

For example, assuming that the point (0, - 4) you do not say that the y-intecept is (0,-4), you say that the y-intecept is -4, because that is the value of the function when x = 0.

Answer:

3

Step-by-step explanation:

find value at  12 =12

find value at 10 =    6

What is the slope of the following graph? (write your answer as a fraction unless divided by 1. Do not use spaces in your answer
alexira [117]

The slope of the graph is 4/5

<h3>How to determine the slope</h3>

Using the formula

Slope = Δ y-axis / Δ x- axis

y2 = -4

y1 = 0

x2 = -5

x1 = 0

Slope = \frac{y2 - y1}{x2 - x1}

Substitute the values into the formula

<em>Slope = </em>\frac{-4 - 0}{- 5 - 0}

Slope = \frac{-4}{-5}

Slope = \frac{4}{5}

Therefore, the slope of the graph is 4/5
